I want to improve the air sealing at the roof/wall interface of our building. The exterior flashing is unsealed, so we are getting a lot of outside air infiltration.

Open-cell spray foam insulation in Triangle is actually cheaper only because its formulation does not need a significant degree of chemical compounds. The open-cell composition of this foam can transform it into a stable and robust air barrier. Even though this doesn't supply any kind of water-vapor filter, it does produce noise reduction. Closed-cell spray foam insulation in Triangle is notably denser and a lot more expensive as compared to open-cell foam. The cellular composition is reduced even more, letting it produce a dominant air barrier in addition to a superior water vapor barrier. This type of spray foam insulation is generally used for roofing jobs or many other outdoor applications for which open cell spray foam is simply not advisable. It can be applied at any place inside the house.

Frequently Asked Questions (FAQ)

The primary distinction between spray foam insulation and other typical kinds of insulation such as fiberglass or cellulose is that spray foam insulation is really an air barrier and thermal barrier all in one. This means that spray foam insulation will do the task of furnishing insulation and air sealing using one product, as opposed to common kinds of insulation that never produce any barrier for the movement of air.
